Abstract: A keyboard as presented here consists of a left and a right array of keys mechanically separated from each other and therefore arbitrarily positionable relative to each other. The keys are couplable to coding units generating the code signals necessary for the control of a data processing faci­lity connected to the keyboard. The two arrays of keys, both essentialy of the same size,contain all the keys necessary for the input of data into the data processing facility and for the control of certain functions including a cursor. In addition to the usual switching device for the choice of capital and small letters and the like, there is an additio­nal switching device so that a number of keys can be coupled alternatively to three or four different coding units.

Abstract: In an encoder replica of a decoder for an input code sequence which corresponds to a code symbol sequence comprising an information symbol sequence and a redundancy bit sequence, a one-bit memory (46) successively memorizes consecutive bits of the input code sequence as memorized bits. An output circuit (62) delivers replica output bits in bit series to a sequential decode controller (43) in response to the memorized bits. In response to the memorized bits and a control signal produced by the controller in response to the input code sequence and the replica output bits, the encoder replica decodes the input code sequence into a reproduction of the information symbol sequence. Preferably, the output circuit is controlled by a position counter (64) giving separate indication of bits corresponding in the input code sequence to the information symbol sequence and of bits corresponding in the input code sequence to the redundancy bit sequence. More preferably, a synchronism shift counter corrects the saparate indication in consideration of a shift in synchronism of the separate indication relative to the input code sequence.

Abstract: The front sheet (38') of a paper web (34) provided with transverse perforations (37') is separated along a separation line (T), which runs adjacently to and at a small distance from a transverse perforation (37'). The paper strip (40) formed in this way is coated with adhesive. Then, the one end of another paper web is applied to this paper strip (40) provided with an adhesive coating (42), without the transverse perforation (37') being covered. The two paper webs are thus spliced together while leaving free the transverse perforation (37'). This makes it possible for the spliced material webs to be folded or separated along this transverse perforation (37'), without leading to difficulties. The "fold memory" created by a prior prefolding at the transverse perforation (37') is maintained.   <IMAGE>

Abstract: An optical transmission system comprises a plurality of optical transmitters (10,12,14,16) coupled by a common channel or bus to an optical receiver. The optical transmitters (10,12,14,16) are operated using TDM (time division multiplexing), each TDM period being word or message length. The optical transmitters each comprise at least one current source (12,14) to drive the light source (10), for example a laser, in response to the data signal, to vary its output power about a steady level which is an average of the maximum and minimum values. The or each current source (12,14) may be so controlled as to increase its output gradually (preferably sinusoidally) to reach the aforesaid mean level at the beginning of a TDM period and to decrease it in the converse way after the period ends. Such an arrangement avoids the need for guard time before and after the TDM time period, thereby increasing channel efficiency, and improves receiver (40-48) sensitivity by reducing quantum or shot noise due to steady light from inactive transmitters.

Abstract: A terminal computer used as a workstation has a display unit (18) which displays a desired number of windows on its display screen, allowing the windows to overlap one upon another. Plural pieces of data speci­fying the positions and sizes of the windows are stored into a memory (38). Data representing the display pri­orities of the windows are stored into another memory (40). A coordinate input device (16), known as "a mouse," is manually operated by an operator, and a cur­sor displayed on the screen of the display unit (18) moves with movement of the mouse (16) on a flat surface. The most current coordinates of the cursor on the screen are stored as present-cursor position data into a memory (32). A window presentation controlling section (30) is provided for comparing the present-cursor position data with the positions and sizes of the windows. When the cursor is detected to have moved into one window on the screen, the window presentation controlling section con­trols the display unit to automatically move this window in front of the other windows on the screen. In this case, the frontmost window is entirely visible, while the other windows are hidden at least partially behind that window.

Abstract: An optical measuring reflector is arranged on the measuring surface, and the device has a first optical interferometer which has a first measuring waveguide, one end of which is connected to a laser and the other end of which points towards the measuring reflector, which reflects the light into the measuring waveguide. The first optical interferometer has a reference waveguide which is coupled to the measuring waveguide, a mirror at one of its ends and, at its other end, a first optoelectric transducer which is connected to the display device for displaying the electrical output signal of the first optoelectric transducer. Moreover, a second optical interferometer is provided which has a second measuring waveguide, one end of which is connected to the laser and the other end of which points towards a reference reflector permanently connected to the device, and a second reference waveguide which is coupled to the second measuring waveguide via a coupling point, and has a mirror at one of its ends and a second optoelectric transducer at its other end. The lengths of the measuring waveguide and reference waveguide of the second optical interferometer differ in each case from the coupling point to the mirror or the reference reflector. The output signals of the first optoelectric transducer and second optoelectric transducer are fed into a comparator which generates an output signal that depends on the difference between the output signals fed in and is fed into a corrector in order to correct the wavelength of the light of the laser and/or to correct the display of the display device. It is possible using this device to measure large lengths in the range of metres and above with high accuracy.

Abstract: A drill bit retaining ring (32) for securing a drill bit (12) to a percussion hammer (14) having a percussion piston (28). The bit (12) has a shank (18) that extends into a chuck sleeve (16, 22) which forms part of the hammer (14). The bit has a set of upper splines (24) and a set of lower splines (30) that allow the bit to move vertically within the chuck sleeve but such movement is limited when the splines abut against the retaining ring (32) which is secured within the chuck sleeve. If the drill bit (12) becomes stuck in the hole, at least the hammer and the associated drill bit can be recovered thanks to the ring according to the present invention which is designed to fracture when a sufficient outward force (i.e. a force in a direction to move the drill string out of the hole) is applied to the drill string thereby releasing the hammer from the bit. However, the ring (32) must be sufficiently strong to withstand the impact forces from the splines (24, 30) under normal operation.
